Answer:

since the denominators are the same we add 3 and 7 in the numerator to get 10/8 or 1 2/8, and we can simplify to 5/4 or 1 1/4.

Hope this helps and brainliest please

How do you solve this problem?

motikmotik

The arcs $AB, BC, AC$ all equal to the third of the perimeter since equilateral triangle divides them like this.

So we need to find a perimeter but we are only given the area.

Let's review,

$A=\pi r^2 \\P=2\pi r$

That means that from area we area able to calculate radius.

$A=\pi r^2\Longrightarrow r=\sqrt{\dfrac{A}{\pi}}$

Insert the numbers,

$r=\sqrt{\dfrac{36\pi}{\pi}}=6$

Then use the perimeter formula to calculate perimeter since radius is known,

$P=2\pi\cdot6=12\pi$

Now divide perimeter by 3 to get length of AB arc.

$AB=\dfrac{12\pi}{3}=\boxed{4\pi}$

Hope this helps.

What is the answer for this problem in the picture

DENIUS [597]

<u>Answer:</u>

The correct answer option is $= 8 x ^ 4 y z ^ 4 \sqrt{2yz}$ .

<u>Step-by-step explanation:</u>

We are given the following expression and we are to simplify it and determine whether which of the given expressions is equivalent to it, assuming $y\geq 0$ and $z\geq 0$ :

$\sqrt { 128 x ^ 8 y ^ 3 z ^ 9 }$

Breaking the terms to get:

$\sqrt { 128 x ^ 8 y ^ 3 z ^ 9 }$ $=8\sqrt{2yz} \times x^{8\times\frac{1}{2} } \times y^{2\times \frac{1}{2} } \times z^{8\times \frac{1}{2} }$

$= 8 x ^ 4 y z ^ 4 \sqrt{2yz}$
